Detailed description of the invention
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4-a, Fig. 4-b, the present invention includes binding clip 1, extension tube 2, handle chassis 3 and handle 4, extension tube 2 is fixedly connected with handle chassis 3, and binding clip 1 tail end is fixedly connected with core bar 6, and binding clip 1 and core bar 6 can slide in the interior front and back of extension tube 2.In handle chassis 3, be provided with the telescoping mechanism 7 that can control the extended or retracted extension tube 2 of binding clip 1, these telescoping mechanism 7 mountain pedestals 8, slide block 10, runner 13 and core bar 6 form, pedestal 8 is fixed in handle chassis 3, pedestal 8 is provided with the first chute 9, slide block 10 can slide in the first interior front and back of chute 9, runner 13 can rotate taking the first rotating shaft 12 on pedestal 8 as axle center, runner 13 is provided with cylinder 14, cylinder 14 can be on slide block 10 the interior slip of the second chute 11, runner 13 is fixedly connected with handle 4, when therefore handle 4 rotates, slide block 10 can slide in the interior front and back of pedestal 8, slide block 10 is fixedly connected with the tail end of core bar 6, so stretching out or bouncing back of binding clip 1 controlled in the rotation of handle 4.
As shown in Fig. 5-a, Fig. 5-b, Fig. 6, pedestal 8 dorsal parts are provided with the device that can stop slide block 10 to slide, this device is made up of the hook protruding 18 on gear 15, spring leaf 17, pin 19, spring 20 and slide block 10, described gear 15 can rotate taking the second rotating shaft 25 on pedestal 8 as axle center, spring leaf 17 can ensure that gear 15 can only one-directional rotation, slide once in slide block 10 front and back, hook protruding 18 can rotate teeth by driven gear 15.Gear 15 is provided with gear hole 16, and pedestal 8 is provided with pedestal hole 22, when gear 15 turns to certain angle, gear hole 16 and pedestal hole 22 are coaxial, and pin 19, under the effect of spring 20, enters in gear 15 and pedestal hole 22, in through the first chute 9, stop slide block 10 to front slide.
As Fig. 7-a, Fig. 7-b, Fig. 8-a, Fig. 8-b, Fig. 8-c, as shown in, binding clip 1 is hook-shaped head end 23 and elastic part 24 by two and forms, and the original state of elastic part 24 is open configuration, in the time that binding clip 1 stretches out extension tube 2 completely, two head end 23 opened with certain angle, are jaw shape; In the time of binding clip 1 partially retracted extension tube 2, two head ends 23, due to the constriction effect closure of extension tube 2, are hook-shaped; In the time that binding clip 1 is retracted extension tube 2 completely, the inclined-plane 26 of extension tube 2 head ends is directly exposed, because extension tube 2 diameters are thinner, is less than 5mm, therefore inclined-plane 26 can directly puncture the body surfaces such as stomach wall and enter in body cavity as sharp orifice, sets up the process of body surface otch while greatly having simplified Minimally Invasive Surgery.
As shown in Fig. 1, Fig. 5-b, extension tube 2 outer wrapping insulant, the shell of handle chassis 3 and handle 4 are made for insulant, pedestal 8 is provided with electrode 21, therefore this invention can merge and use with the medical apparatus and instruments such as high frequency main frame, in operation, binding clip 1 can play the several functions such as separation, crawl, coagulation, TURP.
Product export state of the present invention is gear hole 16 and pedestal hole 22 disalignments, and when operation, binding clip 1 stretches out and is set back in extension tube 2 respectively once, and art is carried out the cleaning of apparatus after finishing, tail end sealing cap 5 is opened, and injects clear water, and binding clip 1 stretches once again, goes out blood stains etc.Along with the continuous use of product, gear 15 constantly rotates until gear hole 16 and pedestal hole 22 are coaxial, pin 19 enters in the first chute 9 and stops slide block 10, and binding clip 1 again cannot stretch out extension tube 2, has therefore prevented from excessively using because of apparatus the application problem of the reality such as the binding clip 1 causing ruptures.
Above-mentioned detailed description of the invention is used for the present invention that explains, instead of limits the invention, and in the protection domain of spirit of the present invention and claim, any amendment and change that the present invention is made, all fall into protection scope of the present invention.
